• Avoid DNS lookups. After resolving the first time, store the value and return it next time. After a time, mark it as invalid, if it is necessary again return the stored one but request it agin
• Be able to load balance in case of multiple records, SRVs and NAPTRs

When i register two clients and try to make a call, the call doesnt go through and is put on hold. The SDP packets dont seem to be right either. Do I need to setup a B2BUA to make the call? SHouldnt a peer to peer call be possible using only the registrar and proxy?

Does NkSIP support B2BUA?
If no, any ideas about implementation or even any example?

nksip_request:reply has a specified return value of

ok | {error, Error}

but in case of success, it actually returns

{ok, #sipmsg{}}

Hi,

I've been playing with nksip, working through the tutorial, and pbx. I would like to know more, especially what is referenced under the 'cookbook'. Are you planning to update this?

Thanks.

How do i serialize RegContact to store in db?

there are two webrtc clients ，nksip used as registrator and also proxy.
the registration to nksip server is ok.
the register message's contact field is just like
Contact: sip:[email protected];transport=ws
;reg-id=1
;+sip.instance="urn:uuid:f81-7dec-14a06cf1"

when A invite B, the nk_register:find will return the registered contact address that can't work (host will be XXXX.invalid). we can use reg_contact record 's nkport to patch this. but when the Invite message‘s ACK message returns, the ACK's request line's UserName and Domain will be Contact's record,and nk_resigter:find will return empty.

the tricky solution is to use nk_register:get_all and search for the right tcp address and port.
the get_all will return an array like below:

    % {armejl7,{sip,<<"aliceQ8wdGvtPgwPDjwFMPyfv8QnzMMZrJIur">>,<<"dev.com.cn">>},
    %     [{reg_contact,
    %          {sip,ws,<<"o4qjt1bm">>,<<"kscovdpk9644.invalid">>,80},
    %          {uri,sip,<<"o4qjt1bm">>,<<>>,
    %              <<"kscovdpk9644.invalid">>,0,<<>>,
    %              [{<<"transport">>,<<"ws">>}],
    %              [],
    %              [<<"+sip.ice">>,
    %               {<<"reg-id">>,<<"1">>},
    %               {<<"+sip.instance">>,
    %                <<"\"<urn:uuid:8d880923-9185-44d1-acdd-76447fd590b4>\"">>},
    %               {<<"expires">>,<<"600">>}],
    %              [],<<>>},
    %          1466146473713000,1466147073,1.0,
    %          <<"0g88hb601851ghie72q9k8">>,1,
    %          {nkport,
    %              {nksip,armejl7},
    %              nksip_protocol,wss,
    %              {0,0,0,0},
    %              10001,
    %              {10,17,41,13},
    %              56987,
    %              {0,0,0,0},
    %              10001,<0.413.0>,<0.412.0>,
    %              #{ws_proto => <<"sip">>}},
    %          [],[]}]}

the real port and wss will be used to fill the uri ,{proxy,uri} will make the message to be routed correctly,but the whole step is ugly,isn't it?
is there any formal solution to solve this webrtc client's bad contact address question?

This is currently used only for two things:

• storing the 'to tag candidate' when a new request arrives without to tag
• storing the reason phrase for responses.

It makes sense to remove this parameters, and add a new one called 'to_tag_candidate'. Reason phrase should be stored in the 'class' parameter.

It doesn't make any sense now

Hi,

I was just wondering why call processes are not showing up in the nksip supervision tree e.g. when using observer. After browsing the source I found out that nksip_call_srv processes are started unsupervised using gen_server:start/3. Is there any special reason for that?

If there is a reason for that (and I'm assuming there is), this could be worth mentioning in the otherwise great documentation. Besides not showing up in monitoring tools having unsupervised processes has the disadvantage that these processes will not be shutdown when the nksip application or the respective sipapp gets stopped.

Regards
Tobias

when I start
$make shell
then
nksip:start(server, #{sip_local_host => "172.21.252.31", sip_from => "sip:172.21.252.31", plugins => [nksip_uac_auto_auth, nksip_uac_auto_register, nksip_registrar, nksip_100rel], transports => "sip:172.21.252.31:5060"}).

after that in the other console I change src/nksip_callbacks.erl
$make

In previous console
nksip:update(server, []).
But callback functions don't change.

Is it normal?

nksip develop https://github.com/NetComposer/nksip/issues/new

make loadtest - broken, can't start the service due the sip_listen format problem
nksip_loadtest:full() - multiple problems, looks like can't start due the port sharing problems

Hello,

Not an issue, just a question:

I use the following code to perform INVITE request:

nksip_uac:invite(Instance, To, [{callback, F}, {add, <<"Session-Expires">>, <<"1800;refresher=uac">>}, {body, nksip_sdp:new(<<"auto.nksip">>, Codecs)}])

Where F in callback option is

 F = fun
        ({resp, 180, Resp, _Call}) -> %% 180: Ringing
        %% Here I need send BYE request
 end,

I tried to use the following inside F function

{ok, Id} = nksip_response:meta(dialog_handle, Resp),
nksip_uac:bye(Id, []);

But got

error sending work {send_dialog,<<"1gnl6P">>,'BYE',[]}: looped_process

Should I extract the dialog_handle from _Call ? Or how to do that in correct way?

Thank you.

I use nksip as a SIP client, for each outgoing call I start separate instance via nksip:start/4, after that do an INVITE request and stop this instance using nksip:stop/1.

During nksip:start/4 nksip creates the uuid_* file and after stopping do not delete it.

Is it normal?

Hi,
i've been testing nksip to work as a proxy in front of some freeswitch servers and make it round-robin the request to these servers.
i can route the calls from phones to freeswitch and back. i used a association table to properly deal with authorization asked by freeswitch.

i now have a situation where A calls B and C wants to pickup the call.
A -> NKSIP -> FS1 -> NKSIP -> B
the problem is that the call that C makes goes into a different freeswitch (as it should ) and freeswitch replies with 302 Moved Temporarely and a header X-Redirect-Server
C -> NKSIP -> FS2 -> NKSIP (302 X-Redirect-Server).

follow_redirects option doesn't work because FS2 doesn't touch the headers (only adds X-Redirect-Server)
AFAIK, i don't have a way to control this, redirect or fork the call.
i need to receive the 302 message, remove the X-Redirect-Server header, associate the call with the new server and tell nksip to retry to the new server.
any hints ?

it would be great to have nksip_sipapp extend to support these flows.

thanks

Hello,

Is this project still alive ? I saw some PR's without any feedback and not too much activity in the last year here.

Silviu

I've stuck trying to implement my_sipapp:sip_authorize/3 callback. I need to return 403 code if there are invalid digest/credentials and 407 code it there is expired nonce in the request. But there are {digest, Realm} = false for both cases and no chances to determine why nksip_auth:get_authentication/2 has rejected the digest. Could you please point me to the right direction?
Thank you.

Got the following error during INVITE request:

 error calling send_work_sync (send): {timeout,{gen_server,call,[nksip_call_router_4...

I've checked the nksip_call_router.erl and found what SYNC_TIMEOUT has value 10 seconds. Is it possible to make this option configurable?

Hello everyone:

I just want to try a erlang sip client and found this one, its good. But when i tried this with nksip_tutorial.erl in '/path/to/nksip/samples/nksip_tutorial', i got this error:

What i need to do? any help would be apprecciated.

most sip phones when register succeeds keep the authorization header and callid and send it again when they re-register. the problem is that the nonce has expired and the phone gets a new proxy-authorization.

i managed to extend the life of nonce by manipulating nksip_store directly on successful registers to avoid extra bonces.

what are the risks that i'm taking here ? (IP/Port/callid) are identical

thanks

After sending an INVITE with a route without "lr", if the call is retried due to authentication, the url and route are swapped.

Hi, any plans to update Cowboy to 1.0? This would make nksip compatible as a dep with erlang.mk.

Is there a plan on adding rebar3 support to the develop branch?

Hi thank you for the awesome project!

I'm starting a sip registrar service in my Elixir project, it works fine with UDP but it returns timeout when trying with TCP!

{:error, {:exit, :timeout}}

Here is my simple project https://github.com/phanmn/ex-pbx

We can start with Iex and using this command to register with TCP

:nksip_uac.register(:client, "<sip:127.0.0.1;transport=tcp>", [{:sip_pass, "1234"}, :contact, {:get_meta, [<<"contact">>]}])

This is a command to register with UDP

:nksip_uac.register(:client, "sip:127.0.0.1", [{:sip_pass, "1234"}, :contact, {:get_meta, [<<"contact">>]}])

Please give me some hints, many thanks!

I'm using v0.5.0.

When I only put one URI in the array, it worked fine.
I'd like to put a couple routes for SIP trunking failover. But it always did parallel forking.

My UriSet is a simple Erlang array of binaries representing uris. According to the doc, serial forking is expected. Not sure what's missing.

we have problem with SDP information
when we send invite request , the SDP information is empty and not in invite request !

Edit :

problem solved 👍

NkSIP currently converts any parameters it recognizes in url and vias to atoms.
For example, <<"lr">> is changed to 'lr'.

There are some problems with this approach:

• the SipApp's developer does not know if a specific parameter is going to be in atom or binary form without looking at the code.
• there is no clear policy for future supported parameters
• it is not clear what to do if a parameter is recognizes as uri and not as via ("tag" for example)

So I think the best solutions is to keep all parameters as binaries.
Any comment?

Hi !

I have a question: why do you limit max udp message size in nksip_connection module ?
-define(MAX_UDP, 1500).

When we send SIP INVITE with big sdp nksip force to use tcp connection. Why?
We've removed the limitation and the udp message was fragmented , which was expected situation due tu Ethernet MTU. It worked.

please check the case where a cisco ip phone sends this header
To: ""unknown"" <sip:[email protected]

that's two times " (double quote)

this happens after we send a 302 Moved Temporarily with
Contact : "unknown" sip:[email protected]

the result is, cannot parse To header

thanks

Hi, this framework seems very interesting. I am curious, what happened to samples from 0.5.0 ? What's the reason they were removed ? Are you interested having them back ?

• Change it to {request, Method} or {response, Code}. This way is consistent, the next of the record is common to requests and responses

ACK has wrong request Uri
The reason - different format for Record route options: <<"lr">> or {<<"lr">>,<<"on">>}
NKSIP Version v0.4.0

Quick fix -
-            case lists:member(<<"lr">>, RouteOpts) of
-                true ->     
-                    DestUri = TopRoute#uri{
+            Lr = lists:member(<<"lr">>, RouteOpts) or lists:member({<<"lr">>,<<"on">>}, RouteOpts),
+            case Lr of
+                true ->
+                  DestUri = TopRoute#uri{

If you pass an #uri{} as a 'to'/'from'/'ruri' meta to nksip_uac functions, you get a cryptic error message like this one:
[error] gen_server <0.374.0> terminated with reason: bad argument in call to erlang:list_to_binary([<<>>,60,<<"sip">>,58,[<<"xxx">>,64],{172,31,0,18},[58,"5060"],<<>>,[],[],62,[[59,<<"tag">>,...]],...]) in nklib_unparse:header/1 line 89

The reason is that domain part of the URI is assumed to be a binary or a string and is used as is. Now I'm forced to use nklib_util:to_host/1 before passing the IP address to a sending function, while it looks like it's better to allow tuple typed IPs as an input and pass them through nklib_util:to_host/1 internally.

PS I'm using the current master branch.
